(Cl.156-526) This invention relates to a road-marking vehicle designed to bedriven or towed on road surfaces for mechanioally laying on andadhesively connecting to said surface a road-marking known material instrip form, as an elasto-plastic compound material, a rubbery fiberreinforced or not reinforced compound material in strip form possessingadhesive character or designed to be provided with an adhesive agentprior to its being laid on and engaged with the road surface.

More particularly, it is an object of this invention to provide a newand improved vehicle as above, designed for mechanically laying down andadhesively applying on road surfaces a continuous or interrupted stripof said road-marking material or materials, and the like, namely forproviding the said road surface with centre-lines or with track-dividinglines or other trafiic signs on road surfaces, prevailingly but notexclusively located lengthwise of the road, the said laying andapplication of strip material being carried on by the hereinafterdescribed assemblies, devices and means of the vehicle of the inventionas the latter is caused to travel on the road surface along a givenpath.

A more specific object of this invention is to provide an improvedroad-marking strip material laying mechanism including strip materialguidingly feeding and laying down rotary means for continuously orinterruptedly putting the said strip material in intimate and adhesivecontact and engagement with the said road surface.

The present invention further contemplates, in a preferred form ofembodiment thereof, the mechanical laying on and adhesive attachment tothe said road surface of spaced lengths of road-marking strip materialof the type considered, and the provision of mechanisms, devices andmeans adapted to overcome the various problems involved in such roadmarking operation, in particular for ensuring the evenly spaced feedingof lengths of said material to the said laying down device and the fulland sure attachment of said lengths in particular, of the re spectiveleading end portions to the road surface.

It is vide, in a strip material laying down vehicle for the aboveoperation, means for supplying a continuous strip of said material,cutter means for cross-cutting the same into successive lengths, holdingmeans for supporting the leading end of the strip coming forth from thesupply means upon each cutting step, feeding and guide means adapted forsuccessively engaging said leading ends and the respective lengths ofstrip material and guidingly to put said ends and lengths in intimatecontact with said road surface, and pressing means adapted fordownwardly urging the said leading ends on the road surface to whichsaid ends have previously been put in contacting relationship, forensuring the full and throughout permanent 'adherence of the stripmaterial, in particular at its end portions, with said surface.

These and other objects and advantages of the invention are in partobvious and in part will be made apparent as this invention proceeds,and the features which are believed to be new and characteristic of theinvention are in particular set forth in the appended claims. Theinvention itself, however, both as to its construction and to its modeof operation will be best understood from the therefore a further objectof this invention to profollowing detailed description of preferredforms of em- I bodiment thereof, when taken in conjunction with the ac-3,957,838 Patented Nov. 7, 1961 2 companying drawings, forming anessential component of this disclosure, and wherein:

FIGURE 1 is a vertical longitudinal elevational view of the assemblyincluding the combined strip material feeding, laying down and pressingdevices, means and elements in continuous strip applying condition ofoperation;

FIGURE 2 illustrates in similar view the feeding means of said assemblyduring the engagement step of the leading end of strip material, uponcutting a length therefrom, while performing a road-marking operation bysuccessively laying down spaced lengths of strip material;

FIGURE 3 is a diagrammatical side elevational view of the generalarrangement of the various essential means in a vehicle of theinvention, including a modified assembly; and

FIGURE 4 is a somewhat simplified view of an exemplificative mechanismadapted for phasedly driving the various co-operating cutter, holdingand feeding devices of the said assembly shown in either the precedingFIGS. 1 and 2 or FIG. 3.

Like reference numerals refer to like parts and components throughoutthe several figures of the drawing, mere structural details and variousvehicle components having been omitted where they are appertaining tothe known art. Referring first to FIGS. 1 and 2 inclusive:

In the form of embodiment shown, the illustrated assembly is intendedfor laying down on and adhesiveiy connecting to a road surface,generally indicated at 10, a strip material indicated at 11a as comingforth from a suitable supply (not shown) and at 11b as being alreadylaid down and adhesively connected on and to the said road surface.

The said supply may consist of a roll of continuous strip material,carried by the same vehicle or by another vehicle towed or driven behindthe material laying vehicle. Motor driven strip material feeding meansmay be provided for feeding the material into the apparatuseshereinafter described, and clutch and/or brake means being provided forensuring the correct continuous and/ or interrupted feeding; such meansmay in their turn be provided with self-acting control means, responsiveto the tension to which the material at 11a is subject, for example, byelectric signalling from a potentiometer 12 (FIG. 4) controlled by aknown tension-metering device generally indicated at 13.

The material laying assembly of FIG. 1 is supposed to be supported bythe frame structure (as indicated at 14 in FIG. 3) of a road vehicle(not shown) adapted to travel in direction A along a given path on theroad surface to be marked. Such vehicle will obviously include steeringmeans and other facilities, such as optical aiming means and the like,for ensuring the correct motion of said vehicle so that the stripmaterial laying devices carried thereby will exactly track the path tobe marked.

The assembly of FIG. 1 includes a strip material pressing structureincluding a frame 15 rotatabiy supporting rollers 16 and 17 at its foreand respectively rear end portions, whereby a substantial space isdefined therebetween, wherein a corresponding length of strip materialmay be subject to a pressure for ensuring the full engagement of thestrip material, in particular, the leading edges of lengths of saidmaterial, upon first contact thereof with the road surface, as occurringat 18. The provision of pressing means capable of effective pressingdown of such leading ends had been proved as essential for actualmarking of road surfaces with interrupted strips, i.e. with spacedlylaid down lengths of strip material.

Obviously such pressing down might be obtained by making use ofdiifering but operatively equivalent means, as by means of relativelymovable roller means, for example, or by making use of temporaryclamping means 3 for the leading end portions co-operating with rolleror slide pressing means, and the like, actuating a pressing downsurface, or a plurality of pressing down surfaces or locations.

In the form of embodiment of FIG. 1 the said pressing down surfaceconsists of the outer face of an endless belt member 19 having a lowerrun 19a supported about said rollers 16 and 17 and an upper runsupported about rollers 20 and 21.

The required downward pressure exerted by the embodiment of the pressingdown surface of FIG. 1 may be attained by the provision of evenly spacedidler rollers '63 supported above said run portion at 19a and downwardlurged as by spring means 64. The whole of structure '15 might bearticulately and/ or downward urgingly connected to the vehicles framestructure (not shown). For example, the modified form of embodimentshown in FIG. 3, wherein the said structure is generally indicated at115, is provided with downwardly urging spring means 65.

In the example given, the strip material is guidedly caused to travelalong and with the said belt member 19, in particular in contactrelationship with the downwardly directed run 1% thereof, by ancillaryguiding means consis-ting, for example, of another belt-like member 22circuitably supported about a plurality of rollers 23 to 26 inclusiveand having a run portion at 22b in adjacent relationship with said runportion 19b for guidingly carrying the said strip material therebetween.The preceding run portion 22a of said ancillary belt member 22 isarranged in juxtaposed relationship with a run portion 27a of a furtherancillary belt member 27, circuited about rollers 28 and 2?.

As comparatively illustrated in FIGS. 1 and '2, the said rollers 23 and28 are movably supported in the assem'blys frame (not shown) forreciprocation in direction 13 and respectively B to set the said beltmembers runs 22a and 27a in the open position of FIG. 2, wherein thesaid runs actuate an inlet mouth adapted for receiving the leading end110 of the strip material upon cross-cutting thereof, and then indirection opposite to B and B" for closing said inlet (FIG. 1) andclampingly engaging therebetwee'n the said material for feeding sametowards position 18 in contact with the road surface 10.

The cutting operation is cyclically performed by a cutting devicegenerally indicated at 39in FIGS. 1, 2 and 4, and this cutting device ispreferably provided with opposed reciprocable cutters or knives 30 and31 or other known means. Said cutting device is displaceably supportedat its slide structure 33, integral with the cutters supporting andguide means at 32, as along rails 34 for back and forth reciprocation indirections A and A".

The leading end 11c of the strip material, resulting upon cross-cuttingthereof, is in its turn temporarily supported and fed in the said inletmouth, in spaced relationship with respect to the previously fed lengthof strip material by holding and intermittent feeding means generallyindicated at 40 and preferably including elongated pincers or clampingmeans 35 and 36 articulated on a structure 37 displaceably supported at38 on rail means, as the said rail means 34 supporting the cuttingdevice 39 (FIG. 1) or different ones (FIG. 4).

The said inlet forming means, cutting means and holding and feedingmeans are phasedly driven for cyclical operation thereof by suitablemechanisms, of which in FIG. 4 an example is given. According to theform of embodiment of FIG. 4, such mechanism includes a cam group 41provided with cam grooves to which levers 42, 43 and 44 are responsive,the said cam group being drivingly connected for synchronization to thematerial carrying belt members, as, for example, by means of bevel gears45, a transmission chain 46 and further gears 47, the roller 21circulating the belt members always acting as the belt driving roller.

The said levers 42, 43 and 44 are drivingly linked, as by means ofpitman levers 48 and respectively 49 and 50, to the said inlet mouthforming components and respectively to the cutting device 39 and to theholding and feeding device 40, the phase relationship of the saidcomponents and devices respective motions being defined by the shape ofthe cam means, according to current knowledge. The amplitude of motionof lever 43 may be amplified by a mechanism including a gear pinion 51in mesh both with a standing rack 66 secured to the assembly framestructure (not shown) and with a rack 67 made integral with thestructure 38 of the said holding and intermittently feeding device 40. 1

In FIG. 3 the general and typical arrangement of the several deviceswhich may be included in a vehicle produced and operating according tothe invention is diagrammatically shown. In said FIG. 3 is further showna modified form of embodiment of the assembly hereinbefore describedwith reference to FIGS. 1 and 2. In such modified form of embodiment, inaddition to a somewhat differing construction of assembly 1115 designedfor downwardly urging the lower run 11% of belt member, the downwardlymoving run 1191) of same member and the ancillary guiding belt member122 are difleringly arranged for adaptation of an adhesive agentapplying device adapted for applying a thin layer or film ofadhesive'substance on the strip material being fed towards the'roadsurface. 7

Such device may consist of a wetting roller .57 fed by means ofintermediate rollers with a liquid adhesive substance from a supply at58, such device being not further described in detail as structurallyand operatively corresponding -to known inking or wetting means ofcurrent product-ion.

Preferably adhesive agents in rapidly evaporating liquid solvents aremade use of for prompt completion of the permanent adhesive engagementof the strip material on the road surface 10. The fast evaporation orvanishing of solvent may be further improved by proper heating of theadhesive wetted or coated surface strip material, as by means of anheating unit'at 59.

The full adherence of the strip material applied to the road surface at10 may be further improved by wetting said surface too with an adhesiveagent, which may be spread on said surface, in front of the position offirst contact of the said strip material on said surface, as by means ofspraying means at 60, and the prompt evaporation of the solvent or thesetting of the agent may be improved by a blast of hot air or othergaseous heatvehicle as from jets 61.

Properly directed air streams, produced say by said jets 61, maybeadvantageously made use of for ensuring the proper advancement of thestrip material, and, in particular of the leading ends of thesuccessively fed lengths of material to be sp'acedly laid on the roadsurface, beneath the material laying and pressing rolling means. Suchutilization of air or gaseous streams and the means provided forproducing same will be therefore considered as appertaining to theancillary devices and means provided for guidin'gly feeding the saidstrip material either in its continuous or-in its interrupted conditiontowards the position of first contact and engagement beneath the layingdown rolling means, and therefore such air or gas jet means will beconsidered as included in the definition of said ancillary materialguide means in the appended claims.

The above described several feeding, laying down and pressing devicesand means are advantageously combined, in a vehicle or in a group ofvehicles according to the invention, with suitable road surfacepreparing means, designed to operate on said surface as the said vehicletravels in direction A.

Such latter means may include, for example, mechanically driven rotarybrushes 52 and 53, one or more rollers 54 of sponge material for suctionof atleast the prevailing-part of water or ther liquid which may existon the road surface, and burners 56 or other source of heat, or jets ofoverheated air or of other gases for burning away or otherwiseeliminating any residual moisture. Such heat ing means may be furtheradvantageously made use of for suitable pre-heating of the road surfaceto improve the adhesiveness of the strip material thereon.

While the invention has been described and shown but in few forms ofembodiment thereof, it is obvious that the invention itself is notlimited to the very details shown, and that several structuralmodifications and variations might be made thereto, according to theart.

It is moreover believed to be evident that the present inventionincludes a plurality of advantageous features, and it will be understoodthat each of the new features described and any combination thereof mayfind useful application in other constructions of road-marking stripmaterial laying down apparatuses differing from the ones described.

Without further analysis, the foregoing will so fully reveal the gist ofthis invention that others can, by applying current knowledge, readilyadapt it for various applications without omitting features that, fromthe standpoint of prior art, fairly constitute essential characteristicsof this invention and, therefore such adaptations should and areintended to be com rehended within the spirit, meaning and range ofequivalence of the invention, as defined in and by the appended claims.
